  34 <p>The operation is used to connect the ports of a test component to the ports of another components.&nbsp;
  35 <ul>
  36   <li>The operation directly connects one port to another with the <b><font face="Courier New">in</font></b> side connected to the <b><font face="Courier New">out</font></b> side and vice versa.;</li>
  37   <li>a port may be connected to several ports (<b><font face="Courier New">connect</font></b> used several times);</li>
  38   <li>the messages (signatures) defined for both ports must match, i.e., the incoming port must be able to receive all outgoing messages from the connected port;&nbsp;</li>

  82 <p>The component of type MyComponentType_CT is created in the first line.<br>
  83 In the second line, its reference (vc_MyNewPTC) is used to point out the port on the side A of the connection (vc_MyNewPTC:Port1_PCO).<br>
  84 On the side B of the connection is the port called Port3_PCO of the main test component.</p>
